BLOOMINGTON, Ind. (AP) – A 20-year-old Indiana University student is accused of selling anti-anxiety pills sent through the mail from his fraternity house.

Andrew Thrall was arrested Tuesday and charged with dealing a controlled substance. Authorities began investigating the prescription drug operation in November.

Bloomington police say Thrall ordered several shipments of Xanax online through a Canadian pharmacy. Police say Thrall had the pills sent to his girlfriend's sorority house, and then distributed them from his fraternity house.

Thrall was booked into the Monroe County Jail on Tuesday afternoon. Online jail records show he posted bond later that day, but they don't list an attorney for him.
